MTL - Weird Wizarding World - Chapter 15 explain

Spiritual energy ecovery brought about fundamental changes throughout the entire world, and posed an imminent threat to it. Chen Yang died in an accident and reincarnated to become a tiny koi fish inside the fish tank in his own home. Just as Chen Yang complained about the unfairness of destiny, he awakened the Evolution System. Thus, with his sister’s feeding, Chen Yang started his insane evolution. As the whole world sank deep into apocalypse, Chen Yang descended from the skies to crush everything.

He had evolved from a tiny koi fish to a gargantuan dragon. “This world shall be ruled by me!” When the fish playing in the waters was frightened by the net, it jumped over the Dragon’s Gate to become a real dragon. This is a story of how a loli raised a giant dragon, and dominated everything.

After the years of fighting monster and Invaders alone, he had become quite adept at surviving. One thing that helped keep him alive was his refusal to get involved with others. He rarely cooperated with teams.One day, Derek broke his rules and decided to lend some help, as the mission didn't seem too hard. He should have stuck to being alone.

Some demon kings have a tyrannical corporeal body, some are experts in illusions.
Some demon kings are proficient in magic, some can even move mountains.
Some demon kings are able to sense things thousands of miles away.

These demon kings rarely appear in the human world. Even if they emerge in the human world, they would reincarnate in human form; assimilating with mankind while seeking to breakthrough realms…
